The situation is further complicated by the mill reject streams that reject undesirable material (tramp metal and noncoal bearing rock) from the mill. Generally, the following steps illustrate the path through a VSM: The raw (coal) feed enters the mill through a central delivery pipe and falls under gravity onto the Grinding Table;
Many problems experienced with ramp rates and flexible operation of PCPP can be traced to coal mills, both the mill itself and the operation and control system. Poor pulverised fuel (PF) distribution to burners has a significant, negative effect on combustion efficiency, wear of equipment and emissions, not to mention economics.
Coal is the mainly energy consumption, so it is the main problem to improve coal fired efficiency for thermal power plant. Traditional ball bill has large power consumption in the process of production, and fineness of pulverized coal is not up to the standard. Great Wall Machinery put forward coal vertical roller mill solution for power plant, which can effectively improve fineness of
